A new type of dementia has been identified and it mimics symptoms of Alzheimer's, the NHS has revealed.

It comes after a new study, conducted by a team of international researchers, reviewed existing studies on brain diseases, later publishing a statement on how the condition should be researched in future.

The research involved experts from 22 universities and research institutes in countries all around the world, including in the UK, Australia and Japan.

As a result of the study, researchers have identified a new form of dementia, bringing together studies on a protein that damages regions of the brain.

The now-identified condition is said to affect almost a quarter of the elderly population and can occur in those who already have Alzheimer's.
